On being attracted to the possibility of a win: reward sensitivity (via gambling motives) undermines treatment seeking among pathological gamblers.

Unfortunately, only a small percent of pathological gamblers seek the professional help they need. In the current study, we test the idea that individual differences in reward sensitivity should predict whether a pathological gambler has sought treatment-the odds of treatment seeking should decrease as reward sensitivity increases. This hypothesis rests on the proposition that reward sensitive pathological gamblers should find treatment seeking aversive because doing so would remove a route to reward. We also tested those motivations to gamble that are positively reinforcing (social affliction and self-enhancement) as a possible mechanism by which reward sensitivity undermines treatment seeking-we did not anticipate negatively reinforcing motivations (e.g., coping) to be a mechanistic variable. Ninety-two pathological gamblers completed a large-scale survey that contained the variables of interest. As predicted, pathological gamblers were less likely to have sought treatment as reward sensitivity increased. Moreover, this relationship was mediated by social affiliation motivations to gamble, but not self-enhancement or coping motives. Reward sensitive gamblers did not wish to seek treatment to the extent that they were motivated to gamble for the social interactions it provides-seeking treatment would cut this avenue of affiliation with others. In light of these results, we suggest health care professionals take reward sensitivity into account when trying to promote treatment seeking, to say nothing of the social affiliation motives that underlie the reward sensitivity-treatment seeking link.

Facilitating responsible gambling: the relative effectiveness of education-based animation and monetary limit setting pop-up messages among electronic gaming machine players.

Although most gamblers set a monetary limit on their play, many exceed this limit--an antecedent of problematic gambling. Responsible gambling tools may assist players to gamble within their means. Historically, however, the impact of such tools has been assessed in isolation. In the current research, two responsible gambling tools that target adherence to a monetary limit were assessed among 72 electronic gaming machine (EGM) players. Participants watched an educational animation explaining how EGMs work (or a neutral video) and then played an EGM in a virtual reality environment. All participants were asked to set a monetary limit on their play, but only half were reminded when that limit was reached. Results showed that both the animation and pop-up limit reminder helped gamblers stay within their preset monetary limit; however, an interaction qualified these main effects. Among participants who did not experience the pop-up reminder, those who watched the animation stayed within their preset monetary limits more than those who did not watch the animation. For those who were reminded of their limit, however, there was no difference in limit adherence between those who watched the animation and those who did not watch the animation. From a responsible gambling perspective, the current study suggests that there is no additive effect of exposure to both responsible gambling tools. Therefore, for minimal disruption in play, a pop-up message reminding gamblers of their preset monetary limit might be preferred over the lengthier educational animation.

The problem with self-forgiveness: forgiving the self deters readiness to change among gamblers.

Self-forgiveness is generally understood to be a mechanism that restores and improves the self. In the current study, we examine the possible deleterious consequences of forgiving the self among gamblers-specifically in regard to gamblers' readiness to change their problematic behavior. At a large Canadian university, 110 young adult gamblers' level of gambling pathology was assessed, along with their readiness to change and self-forgiveness for their gambling. Participants were 33 females and 75 males (2 unspecified) with a mean age of 20.33. Results revealed that level of pathology (at risk vs. problem gamblers) significantly predicted increased readiness to change. Self-forgiveness mediated this relationship, such that level of gambling pathology increased readiness to change to the extent that participants were relatively unforgiving of their gambling. Implications for seeking professional assistance as well as treatment and recovery are discussed.

Where did all the pathological gamblers go? Gambling symptomatology and stage of change predict attrition in longitudinal research.

Attrition can introduce a systematic bias that can negatively affect validity (Cook and Campbell, Quasi-experimentation: design and analysis issues for field settings. Rand McNally, Chicago, 1979). Current longitudinal research in gambling, however, has generally overlooked the reasons for attrition. The current research examined the relationship between pathological gambling symptomatology, stage of change and attrition. Three hundred and seventy-nine participants were contacted 12 months after initially participating in a study on gambling for a follow-up session. Logistic regression revealed those in the contemplation and preparation stages of change reported higher levels of pathological gambling symptomatology and were more likely to drop out of the study compared to those in the precontemplation stage. As predicted, gambling symptomatology mediated the relationship between stages of change and attrition. The implication for longitudinal research on gambling as well as extant findings that have used this methodological approach is discussed.

Placing your faith on the betting floor: Religiosity predicts disordered gambling via gambling fallacies.

Background and aims We examined the potential role religious beliefs may play in disordered gambling. Specifically, we tested the idea that religiosity primes people to place their faith in good fortune or a higher power. In the context of gambling, however, this may lead to gambling fallacies (e.g., erroneous beliefs that one has control over a random outcome). People who are high in religiosity may be more at risk of developing gambling fallacies, as they may believe that a higher power can influence a game of chance. Thus, this research investigated the relationship between religiosity and gambling problems and whether gambling fallacies mediated this relationship. Methods In Study 1, we recruited an online sample from Amazon's Mechanical Turk to complete measures that assessed the central constructs (religiosity, disordered gambling, and gambling fallacies). In Study 2, we conducted a secondary analysis of a large data set of representative adults (N = 4,121) from a Canadian province, which contained measures that assessed the constructs of interest. Results In Study 1, religiosity significantly predicted gambling problem. Conversely, there was no direct relationship between religiosity and gambling in Study 2. Importantly, a significant indirect effect of religiosity on disordered gambling severity through gambling fallacies was found in both studies, thus establishing mediation. The results remained the same when controlling for age, gender, ethnicity, and socioeconomic status for both studies. Discussion and conclusion These findings suggest religiosity and its propensity to be associated with gambling fallacies, which should be considered in the progression (and possibly treatment) of gambling.

Hungry to gamble? Ghrelin as a predictor of persistent gambling in the face of loss.

Ghrelin, a peptide hormone associated with appetite, is also linked to increased reward seeking behaviors, including food, sex, and drug seeking behaviors through the stimulation of the mesolimbic dopaminergic system. Moreover, plasma ghrelin concentrations are increased by cues that predict rewards, suggesting that cues could facilitate cravings and ultimately relapse. In this project we examined the effects of an overnight fast, a manipulation known to increase ghrelin concentrations, on gambling behaviors. We also examined if cues associated with gambling would also increase ghrelin and, if so, we examined if these increases were associated with gambling behavior. One hundred and one (37 females) participants were asked to fast overnight or after breakfast and then asked to complete food and gambling craving questionnaires. Participants were then presented with gambling cues (a casino like environment in the lab) or a control cue (a cubicle with a computer). After the cue, subjects filled gambling craving questionnaires, and were allowed to gamble. Following 25 practice spins, the slot machines were fixed so that all subsequent spins were losses, and the number of spins in spite of losses were quantified. Blood samples were collected throughout the experiment. Results showed that the gambling cues significantly increased ghrelin concentrations particularly in fasted individuals, and that ghrelin concentrations 20 min after the cue were the best predictor for gambling persistence in the face of continued loss (p < 0.05). Our results suggest that cues that predict the opportunity to gamble have an acute effect on ghrelin concentrations that is facilitated by fasting, and that ghrelin concentrations are a significant predictor of gambling persistence.
